Sulphate of Potash (0-0-50)
Another straight fertiliser, this product is very soluble and fast acting, adding essential Potash to soils and composts. SOP helps improve the quality of fruits and flowers and strengthens plant resistance to disease and inclement weather. Symptoms of Potash deficiency can be poor flowering and fruit sets, as well as the leaves turning yellow around the margins which eventually will become brown and burnt. Severe cases show leaf spotting and scorch of foliage.
